I've been having the ABS service light come on during driving. I checked and the stored codes are U1041, C0247, C0242, C0243, C0253.

I saw on another post that code U1041 means that the other computers have lost communications with the EBCM and that is usually due to a loss of power, ground or a bad module. Also, says that the EBCM ground is located on the driver side under the head lamp connections at the radiator support.

My troubles all started after my transmission was rebuilt and a trans cooler was added to the transmission fluid lines. I'm assuming that the ground is not right since the radiator was probably messed with and could have screwed up the ground. Is this EBCM ground location correct and what does it look like?

EBCM ground is under the driver side headlight. 10mm bolt holding on a 12 gauge wire. IIRC
